Serial No. 444,165. I

' United States, residing at Harvard, in the county of Mcllenry and.State of Illinois, have invented a new and usefullmprovement in DoorHangers and Tracks, of which the following is a specification.

Our invention relates to certain new and useful improvements indoor-hangers and tracks, and is fully described and explained in thespecification and shown in the accompanying drawing, in which:

Figure 1 is an elevation of our improved hanger; Fig. 2 is the top planof the hanger; Fig. 3 is a transverse section in the line 3 of Fig. 1,showing the hanger in position in a track; and Fig. 4 is a section inthe line 4 of Fig. 1.

. Referring to the drawing, A is a hollow cylindrical track slotted atthe bottom and supported by brackets, one of which is designated by a,in Fig. 3. The track may be of any well known form as far as our presentinvention is concerned, but in thepreferred form it is constructed afterthe manner set forth, described and claimed inour applicae tion filedMarch 11, 1908, Serial No. 420,470. Two rollers B are provided, eachgenerally spherical in form, the ends being, however, flattened toprovide bearings as illustrated, the rollers being of such curvature asto run easily upon the inner surface of the track A and conformgenerally thereto. The rollers are supported by axles C between whichand the rollers are interposed anti-friction rollers c, the axles beingSupported between the ends of frame-members l). The frame-members l) arepreferably made of cast metal and have their outer ends spaced-apart toreceive between them the rollers B and perforated to receive theaxles-(. whichin practice are riveted or up-set at their ends to holdthe ends of the frame-members together. The framemembers are mediallybrought together and at a point midway between. the axles C to affordpivotal support for a door-supporting loop E, which extends through thebottom slot in the track and is attached to the door by any usual means,preferably by a strap F passed over a rod forming the lower portion ofthe door-supporting loop E.

In lthe preferred form of constructionthe door-supporting loop E ispivoted to the,

sulting friction and binding of said parts.-

The loo E is thus caused to travel 'in a straight inc in the slot andfree from attrition with the sides thereof. Furthermore, the fact thatthe door-supporting loop is pivoted to the hanger-frame-members permitsthe hanger-frame to oscillate with respect to the door so as to take upany inequalities or irregularities in the track surface. This makes thehanger easier to move longitudinally in the track than would be a hangerrigidly secured to the door and relieves strains which would otherwisebe thrown on the connecting device between the hanger and the door whichmight tend to loosen and destroy the same or weaken the wood of thedoor.

We realize that considerable variation is ossible in the details ofconstruction of our improved device. without departing from the spiritof our invention and we do not intend, therefore, to limit ourselves tothe-specific form herein shown and described.

What we claim as new and desire to secure by Letters Patent, is

l. The conrbination with a hollow cylindrical track slotted on its lowerface, of a frame within the hollow of the track, rollers journaled atopposite ends of the frame and engaging the inner surface of the trackand conforming to the Clll'VittLlIG thereof, and a door-supportingportion pivotally secured to the remainder of theframe and extendingthrough the slot in the track, the pivotal support of thedoor-supporting portion upon the remainder of the fraine bemg locatedbelow the plane of the axes of the rollers.

2. The combination '\\lli"l a hollow-cylindrical track slotted on itslower face, of a frame-member comprising two members in separatedmlai-ion Within the same, rollers jmn'nnvlcd bGLWGOD the ends of saidfmn'mmembers, and being: of a contour to mnfmz n t0 the inner surface ofthe track. a (lfiflif-Supporting portion pix-(Rally 500mm! botwe m 7said fra1ne-1nembers extending lhmug'h the 5 slot in the track andadzq'n'ml to bi:- seemed to the (1001', the point of pivotal. suppm'i ofthe door-s11pporting portion Being; lmniod bolnw rho axes of thel'OHQIf-i.
